某电站在对混凝土强度进行日常抽检的过程中,对厂房工程尾水渠齿槽混凝土进行抗冻试验后,发现混凝土抗冻试验结果达不到设计指标要求。为了查找分析原因,避免类似情况再次出现,特开展了一系列室内试验,发现问题并总结了经验。 During the daily sampling of concrete strength, a power plant carried out frost resistance test on the tailrace canal cogging concrete of the plant project and found that the concrete freeze-thaw test result did not meet the design requirements. In order to find out the reasons for the analysis and avoid similar situations from happening again, a series of in-house experiments were conducted to identify the problems and summarize the experience.
